MArcH-Hmnme coresosrrsonl SEECIE'ICATION forming 91m of Letters Patent No. 4.85,103, dated October 25, 1892.

Application filed April 30, 1892. Serial No. 431.3%. (No specimens.)

To ail whom it may concern:

7 die it known that I, JACOB KLEIN, a citizen of the United States, residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Matches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enabie others led in the art to which it uppertains to maize and use the same.

My invention relation to improvements and iiasforitsgencral object" to provide a match embodying such a chem-ical constituency tn white it may be ignited when subject to a. minimum amount of friction, yet it will burn slowly and will be difiicult to extinguish until the stick is consumed.

To the attainment of the foregoing object the invention consists of a match-stick treated as hereinafter described and headed witha compound formed by the following ingredients, combined in substantially the proportions stated, viz: dextrine, twenty pounds; water, eleven pounds six and a half ounces; phosphoruasix pounds ten ounces; mjnium, fifty-four pounds; lamp-black, two pounds. Then add one quart of water and twenty-six pounds of pure nitric acid, preferably 40 Baum, and, after mixingthoroughly, onehun dred and twenty quarts warm water and seventy-two pounds nitric acid. 1

Although in the practice :of my invention 1 prefer to employ match sticks formed by providing a strip of pasteboard or other materiai with a series of lines of perforations,

confined to the same,

whereby a number of matches may be headed and treated at once, yet I do not desire to be as the match-sticks may be headed and treated individuallyfif desired.

In carrying out my invention I first sprinkle or otherwise saturate the match-sticks with aqueous solution of nitrate of potash, which serves to insure a slow tion of the stick, so that it will be dificult to extinguish. After the match-sticks have been thus treated they are headed by dipping, their endsrmthe compoundformed bythe ingrediand elfective. combuscuts before specified, after which they are al- I lowed to dry and are then ready for use.

i It will be found in practice that a small portion of the compound formed 'by the ingredh euts specified upon the end of a match-stick will readily induce combustion on the application of, a minimum amount of friction, and I thereforepreferto place buta slight amount of the compound on-oach match-stick. l

, .Having thus described my invention, what I claim, and desire to secure by Letters Patout, is

A compound for heading matches, consist ing of dextrine, water, phosphorus, minium, lamp-black, and nitric acid-combined in about the proportions stated.

In testimony whereof I presence of two witnesses.
